“…The diagnosis is suspected by chest radiography and can be confirmed by echocardiography [9], including TEE as was done in our patient. The criteria for diagnosis are (1) presence of a normal LA, (2) direct continuity of flow within the LA itself, and (3) no pericardial defect [10].…”

“…LAAA has been classified as intrapericardial or extrapericardial. 31 In addition, associated abnormalities of the conduction system may also predispose to arrhythmia. On the other hand, intrapericardial type is thought to be due to developmental weakness in the wall of left atrium and or appendage.…”

“…Aneurysmal dilatation of the LAA and/ or enlarged left atrium forms a substrate to triggered or reentrant atrial tachyarrhythmia. 31 In addition, associated abnormalities of the conduction system may also predispose to arrhythmia. There is, however, no study proving the origin of the atrial arrhythmias from the LAAA with an electrophysiologic study.…”

Aneurysm of left atrial appendage is rare and often an incidental diagnosis during echocardiography. It is important to recognize this entity since it is associated with cardiovascular morbidity and mortality by predisposing to atrial tachyarrhythmia and thromboembolism. Surgical resection is the standard of treatment in the current literature. Medical management is directed toward the treatment of thromboembolism and atrial tachyarrhythmia.

“…Although this conservative strategy may increase the risk of complications, cardiac surgery also has inherent challenges. Using drug management, monitoring changes in the LAAA and LA are necessary because dilation of the LAAA may trigger atrial tachyarrhythmia [12] and can compress adjacent cardiac structures such as the coronary artery or ventricular wall, as in our case. However, no study has defined the size of LAAA that induce these complications.…”

BackgroundCongenital left atrial appendage aneurysm (LAAA) is a rare cardiac anomaly with potentially serious complications, including life-threatening systemic thromboembolism, atrial tachyarrhythmia, and cardiac dysfunction. Currently, early surgical intervention is generally recommended to prevent these complications.Case presentationWe present a case of congenital giant LAAA in a female patient who successfully completed pregnancy and underwent caesarean section with no obvious complications. Surgical resection of the LAAA was performed 3 years later, at the onset of chest pain resulting from compression of adjacent cardiac structures by the LAAA.ConclusionSurgical resection is recommended for the majority of patients with LAAA because of potential LAAA-related severe outcomes. However, clinical monitoring may be an optional strategy for asymptomatic patients without intra-atrial thrombus or other complications. Precise evaluation with echocardiography and brain magnetic resonance imaging is valuable for the subsequent management of LAAA.
